MARSHES


In between the dunes many large marshes have formed in between earthquakes events and help determine the duration between the earthquakes (Dickinson and Mark, 1994).  The complexity of the biodiversity in these marshes play as a large marker of how much time has elapsed between the events.  Some of these marshes are very complex and great in size; they are the marshes that are usually found between two of the larger dune systems which would be attributed to the larger seismic events (Goff and Wells, 2007).  The size of the marshes is also a contributing factor the complexness of the biodiversity, for example; a small marsh with very large biodiversity compared to a large marsh with the same biodiversity is probably going to fall in between two older dunes (Dickinson and Mark, 1994) because it is more difficult for species to begin to inhabit the smaller marsh due to competition among those already settled there. The marsh shown in figure 3 illustrates the size of one of these marshes that fall between the dunes of the area.

Figure 3 illustrates a marsh that is flourishing as much as some of the marshes in the same area because of the lack of time in comparison to the others.  This marsh falls between two quite large dunes and is roughly 100 meters from the Tasman Sea.  Figure 4 shows a marsh that is between two dunes that are much older and much larger, making the marsh have much higher biodiversity.  The image also shows how the trees congregate in sections on the dune and fill the area out very rapidly (McGowan and Ledgard, 2005), this can be seen by the noting that size of the trees are all very similar, therefore the ages of the trees are also very similar.
